Wireless data transfer
competition is heating up in the entertainment space with a number of
consumer electronics vendors releasing products designed to transfer
video and audiowirelessly around the home at this years' CES show in Las Vegas.
Sony's "TransferJet"
is a a new Close Proximity Wireless Transfer Technology for large data
files like photos, HD images between electronic devices such as mobile
phones, digital cameras, digital video cameras, computers and TVs.
Sony is presenting reference exhibits of this newly developed 560Mbps technology at CES. The company says TransferJet
is an extremely simple wireless technology which eliminates the need
for complex setup and operation. For example, "just touching a TV with
a digital camera enables photos to be instantaneously displayed on the
TV screen".
Designed
as a Universal interface between all consumer electronic devices,
TransferJet 's "Touch & Get" feature will transfer the files
automatically. Users can register their electronic products to enable
TransferJet
to recognize specific devices. For example, by registering only the
devices within their household, users can prevent external data
leakage. Operation is also very intuitive, and as there is no
host/target relationship, data transfer can take place between mobile
phones and PCs for example, as well as between mobile devices.
Even allowing for error corrections and protocol overheads, TransferJet's
physical layer transmission rate is 560Mbps while the effective
physical layer transmission rate is 375Mbps that's fast enough to move
large quantities of data around with a high degree of convenience.
TransferJet
is capable of selecting the appropriate data transmission rate
according to the wireless environment. Even if the conditions for
transmission deteriorate, it will maintain the highest possible
wireless connectivity by automatically lowering the data transmission
rate.
As TransferJet is a close proximity wireless system which
radiates very low-intensity radio waves, it causes almost no
interference to other wireless systems, and there is no impact to
performance even if multiple users simultaneously multipleTransferJet system.
Sony's newly developed "TransferJet
Coupler" is based on electric induction field coupling to deliver
superior propagation performance compared to conventional radiation
field based antennas. It maintains high transmission gain and efficient
coupling in near-field proximity, while providing sharp attenuation
over longer distances to avoid interference with other wireless systems.
